MOLD FOR CONCRETE WALL, COLUMN AND GIRDER CONSTRUCTION.

Application filed July 17, 1917. Serial No. 181,135.

To alliuhom t 'may concern Be it known that I, WILLIAM E. Toon'rn- Lo'rTn, a citizen of tlieUnited States, resid ing` at San Mateo, in the county 0f San Mateo and State of California, have invented certain new and useful Improve ments in Molds for Concrete `Wall, Column and Gfirder Construction, of which the fol- Tliis invention relates to molds or forms for the construction of concrete walls, colunins, girders and the like, land has for its main object f to simplify the construction of the parts of the molds so that they may be readily assembled and. taken apart and reassembled.

Fig. 23 is a perspective view of another form of tie-clip and showing the manner of,

The perpendicular braces 2, and the horizontal braces 4, may be in the form of channel irons. `I also preferably employ, for light constructions, perpendicular reinforcing channel bars 5, which pass up through the mold space and become a part of the wall structure and to wliichmaybe attached light reinforcing members, suoli as wire lath or wire fencing.

As previously stated, an important feature of my invention is the 4manner inl which the system of brace members are secured together by means of tie-plates or clips. While l may employ integral clips such as shown inFig. 14s,. l prefer to make the tie-clips in halves asshown in Fig. 2, the two sections 7, being placed up'on opposite sides to einbrace a pair of perpendicular biaces`f'2 and an intermediate reinforcing member `5 as shown in Fig. 1. The clip sections are then preferably welded to each other at the meeting edges and also to the perpendiculaimembers, the welds being conveniently made by the electric,,oxyacetylcne or other process. In this manner the bracing is not only made very strong and rigid, but the weight of the forms is also distributed along the upright members. After the concrete walls have set and hardened, the sheet metal tie clips can be readily cut by shearing orV by the oxyacetylene torch so that the brace inembers can be renioved. .`The horizontal brace members Il extend between the perpendicular Vbraces 2, determining the spaces there'- bctween Yand uniting the braces into a connected or interlocked system. zontal braces are two or more feet apart and ,areVl preferably notched 'at the ends where These horii curely brace the margins against outward pressure. The vertical joints between abutting form boards may be made tight byV grooving the meeting edges and inserting slip-tongues 10, "which'inay also extend at each end 4into grooves or recesses in the boards above and below, the intermediate boards being also tied together by metal tonguesi12, inserted at suitable distances apart ingrooves or recesses. It is evident that boards of any convenient width may be used and of any different lengths, so that there is practically no waste whatever. rIhe forni boards maybe cleaned and used repeatedly, being preferably treated in a manner to render them impervious to moisture.

The form boards rest upon the tie-clip 7,

i wherev they pass the perpendicular braces and are prevented from falling inward until the cement is poured by the lugs 7` on'the clipswhich project over the edges of the boards. v

IVhen it is desired to face the wall with a veneer finish, such as made from Portland cement, or cements having a magnesite base or veneers made from clay products, I eX- tend the outer ends of the tie-clips and bend i them into oppositely turned lugs 7b as shown in Fig. 5. v by means of a square in Figs. 6 and 7 which are embedded in the facing 6 and tie it to the main body of the wall by means of the tie-clips, as illustrated The lugs 7b may be reinforced plate welded thereto, as shown in Fig. 7. j

In Fig. 15 I have shown another form of tie-clip or plate for use with wood mold forms in which the end rectangular openings` are elongated suficient to permit the forming of the niet-al at the inner ends to burs or tongues 7b, bent in opposite directions so Y that they will cut into the boards to act as anchors to prevent any slipping or movement of the boards. Instead of welding the two sections of the tie-clips together, they may be joined by passing tie wires 15 through holes punched in the ends of the plates and twisting the ends of the wires together. In Fig. 23 I have shown a tie-clip 7 which is stamped from an integral plate or sheet of metal and is provided with flanges 7c which are bent in opposite directions between the form boards and serve to stiii'en the plates against defection due to A the falling of concrete thereon when the wall is in process of pouring.

.In Fig. 18 I have shown the manner of i constructing a corner of the wall with wood forms. The tie-plate'is cut, either as an in- Y tegral plate or in halves 9, to fit'between the inner and outer form boards with anexternal wedge-shaped angle at the outer side and with an internal or rentrant angle at the inner side; An angle piece 11, shown in detail in Fig. 12, is then placed about the double channel vertical brace members 2,

the inner ends being welded, as indicated at 2to the edgesof the plates 9. Each arm of the angle brace 11 is provided with tongues or burs 7L to cut into the `form boards to more securely anchor them against movement. At Vthe outer side ofthe corner I provide rectangular wing plates 1lC which are provided with apertures to receive `the vertical channel bars 2, with room yalso `for the depending hook portions or tongues of the horizontal braces .4, these'wings being welded to theplates 9at ltheir `inner ends as indicated at 11e. I also cut otherfapertures in these plates and form a portion of the metal into tonguesor burs 7a which cut into the mold boards to serve as anchors therefor. One of the form boards 8 may extend outwardly beyond the `other vat the corner, as indicated, therefore avoiding the necessity of cutting theboard. r1`he corner is securelyV of the cement wall.

Instead of using boards forthe mold forms as in Fig. 1, 3, 15 and 18, I may employ sheets of` metal of convenient widths to extend be- Y tween the horizontal braces, `the joints between the sheets being covered by the braces in the manner previously described. I have illustrated the manner of Vusing sheet metal plates 8a in Figs. t, 8, 9 and 10. To form a corner, one sheet may have an end margin Vbent at the required angle, the meeting sheet being fitted into the angle thus formed to close the corner joint, as I have shown in Fig. 4. Within the inner corner I make the perpendicular brace of double strength by placing two channel irons together, while at the outer sideof the corner, I employ twoV separated channel irons. "While I may use integrally formed tie-clips with apertures to fit over `the brace members and the intermediate reinforcing member as illustrated in Fig. 13, I preferto formthe corner tie-clips in several parts as illustrated in Fig. 4. rIhe inside parts 9 embrace the reinforcing channelbar' and bear at each end against the Y diagonally opposite bracemembers 2. The parts 9 are secured tothe inner vertical braces 2` by means of an angle piece 11,

shown in detail in Fig. 12, which engages the braces-on two sides and overlapsthe parts 9, to'which the ends are welded. The small-projection in the angle of the angle iii they may then be welded. `When the parts.

are thus welded togetherandto the'upright braces, avery rigid corner isjformed. The

j parts 9 may be providedwith lugs 7 a to bear against the inside facesof the -forin sheets -82 and hold them in position until the cement is poured. In Figs. 8, 9 and 10, I have illustrated the manner in which my 'forms may be accommodated to walls which turn at various angles. AThe construction will be clearly understood from the'previous descriptionwithout further detailed explanation. The sheets may be of varying lengths, the ends Vbing overlapped and braced byvertical channel bars connected together by tieclips in the manner previously described.

I have indicated in Fig. 16 the manner in which the horizontal brace members 4 are secured in the tie-clips or plates which surround the vertical brace members, `so that thev entire structurek is completely surrounded Iby a continuous'interconnected system of horizontal braces. As previously eX- plained, the apertures inthe ends of the tie plates are cut large enough to provide a slot upon each side of the vertical channel bars .j l 2, to receive the hooked ends of the horizontalA bars. 'The opposite ends of the bars 4 are notched to form 'hooked ends, thenotch la at one end being lcut to forma locking or bayonetslot, while the' opposite end is slotted at 4b to form a somewhat plane curved hook. The end 1b is first inserted into the slot in one ofthe tieclips, the bar 'being held in a downwardly inclined position, as indicated in Fig.'V .16 until the hook engages the slot, and the bar is then' raised in the direction of the arrow into a horizontal position and the end lla is dropped into the slot of the next adjacent tie-plate,. When the end 4J of the next ibar is inserted in the L ing the opposite side of the clip in the notch of the lbayonet notch 4a, as -iiidiacted in Fig. 16. This process is repeated until the last horizontalbrace is laid in place. In order to insert the closing end of the last horizontal Abrace in the clip at the last upright, which has already received the first Vend of thefirst horizontal brace, it is necessary to cut the slots in this clip somewhat Wider than the slots inthe others in order that the end of la of the last brace may be slipped into position. There will, therefore,

remain a` small space betweenthe end of this last horizontal brace and the side ofthe adjacent upright channel bar. This clearance space maybe closed by means of a metal key driven thereinto and the whole tier will thus belocked by an interconnected chain of horizontal brace members. I have shown in Fig. 17 another method of securing the end of the last horizontal brace in the series. The upright at this connecting clip may be cut with its ends tapering into vwedges as indicated in Fig. 17. After the last horizontal member has been slipped into position, the upper portion of thev upright may be driven downwardly to thereby wedge the boards 'tightly together. In each case,

therefore, thehorizontal boards form an intercoiinected continuous cha-in surrounding the entire mold form of the wall.

It is frequently desirable to splice or connect the ends 'of upright or vertical brace members so that they will fo-rni, in edect, a continuous brace. In Figs. 19, 20 and 21 I have shown a very eihcient slip joint for thus uniting the meeting ends of vertical brace members. Each of the meeting lends of the vertical channel bars may be provided Vwill be apparent that the verticall channel bars may ,be united by slightly separating their ends until the heads of the screws have been inserted through the larger portions of the slots 20 and then lowering'the upper brace until lthe necks of the screws have entereduthe narrower portions of the slots 20, the notches 21 fitting around the neck of the central screw.

The several advantages to be derived from the use of my mold forms and my method of assembling the parts will be especiallyappreciated by constrimting engineers and those familiar with the present methods of pouring concrete walls. j I have greatly reduced the number of parts required for setting up the molds and have taken advantage of the recent advance in rapid welding methods which enables me to use standard rolled iron shapes, such as channel bars, to-

gether with a few shapes of clips which may be stamped out of sheet metal in certain standard sizes. When boards are employed they can be any convenient width and of random lengths different widths being used to make up the desired height. Likewise when sheet metal is used for the sides of the forms, they may be of any suitable Width and in varying lengths, and ineither case the boards and metal sheets can be Aused again and again. Y y

My improved tie-clip enables me to readily yassemble the vertical and horizontal channel iron braces and to unite them into an interlocked system which affords ample strength and rigidity. It will be understood that I can employ other` rolled shapes such as I-beams, if desired or more convenient, and these are included in vthe term channel beams.

I have described in detail theparticular construction shown in the accompanying f drawings for the purpose of illustrating an 1 embodiment of my invention, but I wish it understoodthat various changes and modications can be made therein to suit varying conditions within the scope of my claims and without'departing from the spirit of my invention.
